The Battery Disconnect Switch
The battery disconnect switch is located in the R/H side wall trim panel of
the boot. When actuated, power to all control modules is disconnected and
only ‘keep alive memory’ power is maintained. Thus the quiescent power
drain on the battery is greatly reduced.
To maintain the battery charge level, press the battery disconnect switch and
use the battery conditioner to charge the battery whenever the vehicle is to
be out of use for some days.
If the battery disconnect function is used in conjunction with the battery
conditioner, the vehicle may be stored for many months without additional
battery maintenance.
Caution: The vehicle security systems will be totally disabled when the battery
disconnect switch is used. The vehicle will be secured only by the mechanical door
locks. Ensure that the vehicle is stored in a secure location.
Caution: Close and lock the doors before disconnecting the battery. The door window
seals will be damaged if the door is closed or opened when the battery is disconnected.

1-F-53 Window Controller Memory Check
With the alarm off and the doors unlocked, open and then close each door
in turn. If the door window drops on opening and rises on closing the door,
the window controller memory is good. If the windows do not drop and rise
correctly, reset the window controllers as follows:
Window Controller Memory Reset Procedure
1. Sit in the drivers seat with the doors closed. Turn on the ignition switch.
2. Press and hold down the window Down button until the window drops
to its maximum down position in one movement.
3. Press and hold the window Up button until the window rises to its
maximum up position in one movement.
4. Switch off the ignition, step out of the car and close the doors. Perform
the Window Controller Memory Check to ensure that the window
maximum up and down positions have been correctly reset.
Headlamp Ventilation
In very humid conditions some condensation may accumulate within the
headlamp pod enclosures whilst the engine is stopped. When the vehicle
is running and the air conditioning is switched on, the headlamp pod
enclosures are automatically vented and any condensation will clear within
a few minutes.
For rapid headlamp ventilation, use the following settings: A/C On, Fan
speed 3, Interior vents all closed. If the condensation does not clear quickly,
consult your Aston Martin dealer.
